In the near-ish future, Earth is invaded by nasty aliens called the Waldaster, and only the space knight Tekkaman can defend the planet. Tekkaman’s other identity, Joji Mionami, is able to transform into earth’s savior using Tekset system technologies, and he has an ax – or a space lance, actually – to grind with the Waldaster, who killed his dad (along many other earthmen). On top of that, Joji and his spacefaring pals on the Tekkaman team are searching for a new home for the people of the quickly dying planet Earth. He’s got a lot on his plate.
